Estimador de rendimento de lenha

Estime quantas peças de lenha, quanto volume empilhado e quantos sacos você pode obter a partir do diâmetro da tora, comprimento, tamanho-alvo da lenha e taxa de defeito.

Alterne entre lenha redonda e rachada enquanto ajusta ao mesmo tempo o fator de empilhamento e a capacidade do saco.

Safety notice

Esta ferramenta estima apenas quantidades. Não a use para decisões de segurança sobre cortar, dividir, mover ou carregar toras.
Verifique separadamente a capacidade da máquina, o equipamento de proteção, as condições de armazenamento e as normas locais.

Como usar

1

Enter the log count, log diameter, log length, and defect rate.
2

Choose the firewood shape, then enter the target length and cross-section.
3

Set the stacking preset and bag capacity.
4

Review pieces, stacked volume, and bag count in the result cards.

Examples

Standard round firewood

Entrada

10 logs, diameter 280mm, length 3.6m, defect 12%, firewood length 330mm, diameter 80mm, stacking factor 0.70, bag 100L

Saída

About 1,176 pieces / about 2.79 m³ / about 27.9 bags (purchase guide 28)

Imperial site example

Entrada

8 logs, diameter 10in, length 8ft, defect 10%, firewood length 16in, width 4in, thickness 4in, stacking factor 0.65, bag 3.5ft³

Saída

About 212 pieces / about 48.3 ft³ / about 13.8 bags (purchase guide 14)

Formulas

Log volume = π × (diameter ÷ 2)^2 × length × log form factor
Usable volume = log volume × log count × (1 - defect rate)
Pieces = floor(usable volume ÷ one-piece volume)
Stacked volume = finished firewood volume ÷ stacking factor
Bags = stacked volume ÷ bag capacity

Observações

Diameter is treated as an average estimate. Use the log form factor if taper is strong.
Stacking factor and bag capacity vary with site practice, packing density, and firewood size.
Charcoal yield is out of scope.

Perguntas frequentes

Is the log diameter average or top-end?

It is treated as an average diameter. If you only know the top-end diameter, adjust it to a nearby average.

Are pieces rounded up?

Completed pieces are floored, while bag count is rounded up as a purchase guide.

What if I do not know the bag capacity?

You can still use the piece count and stacked volume. Bag count stays hidden until you enter a capacity.

Can I type values like 8ft or 330mm?

Yes. Each field accepts bare numbers using the selected default unit, and values with a unit suffix.

Does it calculate charcoal yield too?

No. Charcoal production uses different conditions and is out of scope.
